Description

Technical Field

[0001] This utility model belongs to the field of epoxy resin board technology, specifically relating to an adhesive coating device. Background Technology

[0002] In experimental sampling or coating performance testing, different types of material boards typically require surface coating with resin-based adhesives to simulate the bonding effect in real-world applications. Especially during scientific research experiments, the required dimensions of the boards to be coated and the thickness of the adhesive coating often vary, making it impossible to process them using standardized automated equipment. Therefore, in existing laboratory environments, most adhesive coating operations are still completed manually by scraping the adhesive.

[0003] The existing manual glue application methods generally suffer from the following technical problems:

[0004] Firstly, because the boards are not fixed or are not fixed securely, they are prone to moving or warping during the glue application process, which in turn causes the glue application trajectory to deviate and affects the uniformity of the glue thickness.

[0005] Secondly, the existing device lacks a structure for precise control of the angle and pressure height of the scraping tool during the scraping process, making it difficult to uniform the scraping thickness and thus affecting the stability of the experimental results.

[0006] Third, after the glue application is completed, residual glue usually adheres to the surface of the tool or workbench, which is difficult to recycle and can easily lead to material waste and surface contamination. Utility Model Content

[0007] To address the problems existing in the prior art, the purpose of this utility model is to provide a glue coating device that can achieve stable clamping, adjustable coating thickness, high operating precision, and glue recovery function, thereby improving the work efficiency and quality control capabilities in the experimental glue coating process.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an adhesive applicator, comprising a base, first track rods symmetrically arranged on both sides of the upper surface of the base, a bidirectional threaded rod rotatably installed on the upper surface of the base, vertical columns at the four corners of the base, and two second track rods arranged above the space between two columns on the same side, the second track rods being parallel to the first track rods;

[0009] Two movable clamping plates slide between the two first track rods. The bottom of the movable clamping plates is screwed onto the bidirectional threaded rod. The two movable clamping plates are used to clamp and fix the plate.

[0010] Slider blocks are slidably mounted on the surfaces of the two second track rods on the same side. A rotating shaft is rotatably mounted between the two sliders, spanning across the base. A scraper is slidably mounted on the surface of the rotating shaft.

[0011] Furthermore, the movable clamp has an L-shaped cross-section with the outer side concave downwards. A glue collection box is installed on the outer side of the movable clamp, which is flush with the upper surface of the movable clamp. The glue collection box is used to collect excess glue.

[0012] Furthermore, central support blocks are symmetrically arranged on both sides of the upper surface of the base. The central support blocks are used to support the center position of the plate. The central support blocks are flush with the upper surface of the movable clamping plate. Positioning protrusions are arranged on the upper surface of the movable clamping plate near the glue collection box.

[0013] Furthermore, sliders pass through both ends of the rotating shaft, and a groove is formed on the surface of the rotating shaft along the axis. A slide block is slidably installed inside the groove, and a scraper is installed at the bottom of the slide block. The scraper is inclined, and a handle is provided on the top of the slide block.

[0014] Furthermore, a swing plate is provided at one end of the rotating shaft. The swing plate is parallel to the scraper and the ends of the two are flush. The swing plate is placed outside the slider. One of the sliders has height markings uniformly engraved on its outer surface. The bottom end of the swing plate corresponds to the height markings.

[0015] Furthermore, a support platform is provided on the upper outer side of the slider, and a screw is vertically and rotatably installed on the upper surface of the support platform. A connecting plate is screwed onto the surface of the screw, and limit rods are symmetrically provided at the bottom of the connecting plate.

[0016] Furthermore, both limiting rods penetrate the support platform, and the bottom ends of the two limiting rods limit the maximum angle of the swing plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model achieves rapid clamping and stable fixation of plates of different sizes by setting a combination structure of a first track rod, a bidirectional threaded rod and a movable clamping plate on the base. It solves the problem that the plates are easy to shift or shake during the existing manual glue application process, and effectively improves the stability of glue application and the accuracy of operation.

[0019] This utility model sets a central support block on the base, which is flush with the upper surface of the movable clamping plate. This provides support for the center position of the clamped plate, preventing the plate from sinking or deforming during the gluing process under stress, and improving the uniformity of the gluing thickness and the consistency of the process.

[0020] This utility model sets up a sliding slide and scraper assembly, and installs it on a rotating shaft. The scraper achieves linkage adjustment of angle and height by rotating the shaft. At the same time, with the help of the synchronous swing plate and the height scale, it achieves precise control of the glue thickness, overcoming the defect of uneven glue thickness in the traditional manual method.

[0021] This invention features a height-adjustable limiting structure on the outside of the slider. The screw, in conjunction with the connecting plate, drives two limiting rods to limit the angle of the swing plate, thereby ensuring that the maximum angle is consistent when the scraper performs bidirectional scraping. This ensures that the coating thickness remains consistent in both forward and reverse operations, significantly improving the repeatability and precision control of experimental data.

[0022] This invention features a glue collection box on the outside of the movable clamping plate, flush with the surface of the clamping plate. This box can collect excess glue from the end of the plate in a timely manner, preventing glue residue from remaining on the surface of the device and causing waste and pollution. It solves the problem of difficult glue recycling in traditional manual operation, and improves material utilization and the cleanliness of the experimental environment. Attached Figure Description

[0030] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0031] refer to Figures 1-6As shown, an adhesive applicator includes a base 1. First track rods 11 are symmetrically arranged on both sides of the upper surface of the base 1, providing a guiding sliding function for the clamping assembly. A bidirectional threaded rod 12 is rotatably mounted in the middle of the upper surface of the base 1 in the horizontal direction. The two ends of the bidirectional threaded rod 12 are supported on the base 1 and can be manually rotated externally to drive two clamping plates to move towards or away from each other via their two threaded segments, thereby achieving adaptive clamping of plates of different widths. Columns 13 are vertically fixed at each of the four corners of the base 1. The tops of the columns 13 are connected to two second track rods 14 by screwing or welding. The two second track rods 14 are arranged parallel to each other and maintain a parallel relationship with the first track rods 11, serving to support the rotating shaft 4 and its moving mechanism and forming a high-level guiding structure.

[0032] Two movable clamping plates 2 are slidably installed between the two first track rods 11. The bottom inner side of each movable clamping plate 2 is fixed with a nut assembly that matches the bidirectional threaded rod 12. By rotating and pushing the bidirectional threaded rod 12, the two movable clamping plates 2 can clamp the plate laterally along the direction of the first track rod 11. The top surface of the two movable clamping plates 2 is a plate support platform, which can provide a stable lateral clamping support for the glued plate, and at the same time has a certain height to match the height level of the bottom center support block 15.

[0033] Slider 3 is slidably mounted on the outer surface of the two second track rods 14 on the same side. The inner cavity of the slider 3 is slidably connected to the second track rod 14 to ensure that it moves smoothly along the guide direction. A rotating shaft 4 is rotatably mounted between the two sliders 3. The rotating shaft 4 is fixed to the slider 3 by bearing support structure at both ends and can be adjusted horizontally. The rotating shaft 4 is used to realize the synchronous adjustment of the angle and height of the scraper 52, thereby improving the accuracy of the coating thickness control. A scraper assembly is also slidably mounted on the surface of the rotating shaft 4. The scraper assembly includes a slide seat 5 that slides along the axial direction, and the scraper 52 is mounted on the bottom of the slide seat 5.

[0034] refer to Figures 1-3 As shown, the movable clamping plate 2 has an L-shaped cross-section, with the outer part recessed downward to form a groove structure, which is used to enhance the structural strength of the clamping plate. A glue collection box 22 is installed on the outer part of the movable clamping plate 2. The glue collection box 22 is fixed to the outer edge of the clamping plate by snap-fit ​​or screw connection. The upper opening surface of the glue collection box 22 is flush with the upper surface of the clamping plate 2, which is used to collect the excess glue that overflows from both ends of the board during the glue scraping process, effectively reducing glue waste and facilitating recycling.

[0035] refer to Figure 3As shown, central support blocks 15 are symmetrically arranged on the left and right sides of the upper surface of the base 1. The central support blocks 15 are located in the middle between the movable clamping plates 2. The height of the central support blocks 15 is consistent with the upper surface of the movable clamping plates 2. They are used to provide stable support for the center position of the plate after installation, effectively preventing the plate from deforming or uneven glue thickness due to its own weight sinking. A positioning protrusion 21 is provided on the upper surface of the movable clamping plate 2 near the glue collection box 22. The positioning protrusion 21 is a short column structure and is set on the upper part of the clamping plate. It is used to abut the end of the plate for positioning and to prevent the plate from sliding longitudinally during the glue application process.

[0036] refer to Figure 4 As shown, the two ends of the rotating shaft 4 are respectively mounted on two sliders 3. The surface of the rotating shaft 4 has a groove 41 along the axial direction. The groove 41 is a semi-closed long groove structure, which is used to limit the movement trajectory of the slide block 5. The slide block 5 with an I-shaped cross section is slidably installed inside the groove 41. The slide block 5 and the groove 41 slide together to realize the linear displacement operation of the scraper 52 in the axial direction of the rotating shaft 4. The scraper 52 is installed at the bottom of the slide block 5. The scraper 52 is inclined and its angle is adjusted by rotating the rotating shaft 4. The top of the slide block 5 is provided with a handle 51 for controlling the horizontal movement of the slide block 5 and the scraping operation.

[0037] refer to Figures 4-6 As shown, a swing plate 42 is provided on the outer side of one end of the rotating shaft 4. The swing plate 42 is parallel to the scraper 52 of the slide block 5 through a connecting mechanism, and the ends of the two are kept flush in the vertical direction to synchronously reflect the angle change of the scraper. The swing plate 42 is located on the outer side of the slider 3. The outer surface of the slider 3 at the corresponding position is uniformly engraved with height lines 31. The height lines 31 are auxiliary marks for reference to the angle of the scraper. The bottom end of the swing plate 42 is always aligned with the height lines 31. By reading the scale, the height of the lower end of the scraper 52 relative to the board can be quickly determined, which makes it easy to adjust the glue thickness.

[0038] refer to Figure 4 As shown, a support platform 32 is provided on the upper outer side of the slider 3. The support platform 32 is fixed to the top of the slider 3 and is fixed by screws to support the height adjustment structure. A screw 33 is vertically rotatably installed on the upper surface of the support platform 32. The screw 33 is threadedly engaged with the support platform 32. Rotating the screw 33 can drive the connecting plate 6 screwed on it to move up and down in the vertical direction. The connecting plate 6 is a rectangular plate structure. The bottom of the connecting plate 6 is symmetrically provided with limit rods 61. The two limit rods 61 are arranged in the vertical direction and extend downward through the support platform 32. The limit rods 61 are used to limit the maximum position of the rotation angle of the swing plate 42, thereby controlling the maximum tilt angle of the scraper 52 during operation, ensuring that the lower end face height of the scraper 52 is consistent when applying glue in both directions, and ensuring that the glue thickness is uniform and stable.

[0039] The working principle of this utility model is as follows: During the experimental sample testing stage, the size of the board and the thickness of the adhesive are different each time. Therefore, manual scraping is often used. When using it, the board is placed on the upper surface of two movable clamping plates 2, and the bidirectional threaded rod 12 is rotated to bring the two movable clamping plates 2 closer to each other so that the two ends of the board abut against the positioning protrusion 21 to fix it. The bottom center position of the board is supported by the central support block 15 to ensure its stability and prevent bending during adhesive application. After clamping and fixing, the thickness of the adhesive is adjusted. The slide 5 has an I-shaped cross section, so the slide 5 can only move along the axis of the rotating shaft 4. The scraper 52 and the swing plate 42 always keep in line. The angle and bottom height of the scraper 52 are adjusted by rotating the rotating shaft 4. The height of the lower end of the scraper 52 is judged by the cooperation of the swing plate 42 and the height mark 31. Then, the screw 33 is rotated to control the height of the connecting plate 6, and then the height of the limiting rod 61 is controlled so that the bottom ends of the two limiting rods 61 limit the maximum angle of the swing plate 42.

[0040] When using, pour epoxy resin glue onto the surface of the board, hold the handle 51 and rotate it to one side until the swing plate 42 is limited by the limiting rod 61. At this time, the angle of the handle 51 is at its maximum and the height of its lower end face is consistent with the set value. Push the rotating shaft 4 to move along the second track rod 14 to achieve glue application. After a single glue application is completed, move the slide block 5 out of the board area, then rotate it in the opposite direction and move it laterally along the slide groove fixing rod 41 by one width. When the scraper 52 rotates in the opposite direction to its maximum angle, it is also limited by another limiting rod 61 to ensure that the height of the lower end face of the scraper 52 is consistent regardless of the direction of glue application, thereby ensuring consistent glue thickness and ensuring glue application quality.

[0041] When the scraper 52 moves to the very end, excess glue will enter the glue collection box 22 for collection, reducing waste.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
